Definitions

  • US 2002/109358 A1 describes a wind turbine with a rotor and a plurality of vanes.
  • the rotor is rotatably arranged around the rotation shaft of the wind turbine according to a rotating movement around the rotation shaft.
  • a plurality of blades is point-symmetrically fitted around the rotation shaft.
  • the blades are arranged such that they can drive the rotor according to the rotating movement around the rotation shaft under the effect of the wind.
  • the blades extend from one end to only a distance from the rotation shaft and thus delimit a cavity which comprises the rotation shaft.
  • the wind turbine also comprises a plurality of vanes.
  • the vanes are arranged point-symmetrically around the hollow rotor in order to guide wind to the blades of the rotor.
  • the wind which is guided to the rotor by the vanes drives the hollow rotor according to the rotating movement.
  • the vanes extend virtually from the ends of the blades to an end of the vanes.
  • vanes and the blades when they are in line with one another, they merge into each other at their adjacent ends at virtually the same curvature virtually mathematically tangentially in a plane virtually at right angles to the rotation shaft.
  • curvature of the blades, at the location of their first ends extends radially to the rotation shaft in this plane and the curvature of the vanes in this plane is described by a part of a virtually logarithmic spiral, also known as a “spira mirabilis”.
  • the value b is also referred to as the growth factor.
  • mathematically tangential means that the first derivative of the curve of the blades and the vanes is constant at the transition between the blades and the vanes in the virtually horizontal plane.
  • the velocity of the wind which drives the rotor can be increased by guiding the wind over the vanes, in which case the vanes are curved in such a manner that the vanes compress a volume of wind at a certain velocity to a smaller volume of wind at a greater velocity, it has been found that such an increase of the wind velocity is associated with a loss of laminarity of the wind, again resulting in a loss of energy to turbulence and often the required rotary velocity of the rotor can again not be reached.
  • the inventor has found that the vanes make it possible to increase the velocity of the wind present around the wind turbine without significantly disturbing the laminarity of the wind, so that it becomes possible still to increase the rotary velocity of the rotor at the naturally occurring wind velocities.
  • the vanes may rotate around the rotation shaft of the rotor with respect to the rotor depending on the direction of the wind in order to make better use of the wind velocities present.
  • not only the blades, but also the vanes of a wind turbine according to the present invention are arranged point-symmetrically around the rotor in order to increase efficiency further.
  • the curvature of the blades of a wind turbine according to the present invention is preferably crescent-shaped in a plane virtually at right angles to the rotation shaft.
  • the height of the rotor is substantially equal to the golden ratio multiplied by the diameter of the rotor. It has been found that a deviation of at most 3% from this ratio is preferred in this case.
  • the wind turbine comprises means for converting the rotating movement of the rotor into electrical energy. It has been found that such means make it possible to generate electrical energy using the wind turbine according to the present invention.
  • the invention also relates to a building comprising a roof which at least partly covers the building, in which said roof comprises a roof edge and in which the building comprises a wind turbine according to the present invention on the roof of the building, in which the rotation shaft of the wind turbine is arranged virtually parallel to the roof edge. It has been found that the building then forms an additional wind catch for the wind turbine. It has been found that, in particular if the building is located in areas with a relatively high wind velocity, such as a coast, such as for example the Belgian coast, it is still possible to generate sufficient energy in a relatively silent manner.
  • FIG. 4 shows a top view of a rotor to which a compressed air hose is connected.
  • FIG. 6 shows a perspective view of a further preferred embodiment of the wind turbine according to the invention.
  • FIG. 7 shows a cross section of a preferred embodiment of the wind turbine according to the invention, cut through the rotation shaft.
  • the rotor ( 2 ) which is rotatably arranged around the rotation shaft ( 3 ) of the wind turbine ( 1 ) according to a rotating movement around the rotation shaft ( 3 ) comprises a plurality of blades ( 4 ) which are fitted point-symmetrically around the rotation shaft ( 3 ). Air flow ducts ( 11 ) extend between the blades ( 4 ).
  • the rotor ( 2 ) which is illustrated in the figures is a hollow rotor ( 2 ).
  • the hollow rotor ( 2 ) may, for example, be placed on the ground, in which case said ground may serve as a limiting element, or may be installed on a baseplate ( 9 ), the shape of the base surface of which is substantially similar to the rotor ( 2 ).
  • the rotation shaft ( 3 ) has a first end and a second end, with the second end being fitted rotatably on the baseplate, if present.
  • the rotation shaft ( 3 ) may be either a physical rotation shaft or a virtual rotation axis.
  • Materials which are suitable for producing the real rotation shaft ( 3 ) are, for example, materials which can withstand weather conditions and are sufficiently strong to withstand the constant action of the wind which may vary greatly in strength, for example steel or steel alloys, such as stainless steel.
  • FIGS. 1, 2, 6 and 7 show a wind turbine ( 1 ) with a vertical rotation shaft ( 3 ) and FIG. 3 shows a plurality of wind turbines ( 1 ) in which the rotation shaft ( 3 ) is arranged horizontally.
  • the dimensions of the rotor ( 2 ) are determined by the diameter and the height of the rotor ( 2 ). In a preferred embodiment, the height of the hollow rotor ( 2 ) is substantially equal to the golden ratio multiplied by the diameter of the rotor ( 2 ).
  • the hollow rotor ( 2 ) may preferably be covered by a cover plate ( 6 ) in which a perforation is provided for the rotation shaft ( 3 ).
  • a cover plate ( 6 ) delimits the air flow ducts ( 11 ) between the blades ( 4 ) in order to optimize the flow of air and protects the hollow rotor ( 2 ) by preventing, for example, objects from ending up in the rotor ( 2 ) from above and thus from impeding the operation of the wind turbine. It is particularly advantageous if a baseplate ( 9 ) and a cover plate ( 6 ) are present which are of virtually identical shape and are fitted symmetrically around the rotation shaft ( 3 ).
  • the blades ( 4 ) are made of a lightweight material, such as for example a plastic, such as polyvinyl chloride (PVC), polyethene (PE), polypropene (PP), polystyrene (PS), polyurethane (PUR), polyester or polyethylene terephthalate (PET), or a lightweight metal, such as aluminium, but a canvas made from a suitable type of textile is also a possibility.
  • a plastic such as polyvinyl chloride (PVC), polyethene (PE), polypropene (PP), polystyrene (PS), polyurethane (PUR), polyester or polyethylene terephthalate (PET), or a lightweight metal, such as aluminium, but a canvas made from a suitable type of textile is also a possibility.
  • PVC polyvinyl chloride
  • PE polyethene
  • PP polypropene
  • PS polystyrene
  • PUR polyurethane
  • PET polyethylene terephthalate
  • Suitable materials for producing the vanes ( 5 ) are, for example, metals, such as steel, aluminium or a metal alloy, or a plastic such as polyvinyl chloride (PVC), polyethene (PE), polypropene (PP), polystyrene (PS), polyurethane (PUR), polyester or polyethylene terephthalate (PET), depending on the environment in which the wind turbine ( 1 ) is to be placed.
  • PVC polyvinyl chloride
  • PE polyethene
  • PP polypropene
  • PS polystyrene
  • PUR polyurethane
  • PET polyethylene terephthalate
  • Air flow ducts ( 12 ) extend between the vanes ( 5 ) and are provided in order to guide wind towards the blades ( 4 ) of the hollow rotor ( 2 ) and thus to drive the hollow rotor ( 2 ) according to the rotating movement, with the vanes ( 5 ) extending from a first end ( 15 ) virtually at the location of the second ends ( 14 ) of the blades ( 4 ) to a second end ( 16 ) of the vanes ( 5 ) which is arranged further from the rotation shaft ( 3 ) than their first end ( 15 ).
  • twice as many vanes ( 5 ) are provided as blades ( 4 ).
  • the figures also show that the vanes ( 5 ) are much larger than the blades ( 4 ), as a result of which the rotating part of the wind turbine ( 1 ) remains relatively small compared to the overall size of the turbine ( 1 ), thus limiting wear and noise pollution resulting from rotation of the rotor ( 2 ).
  • FIG. 1 shows that when the vanes ( 5 ) and the blades ( 4 ) are in line with one another, they merge into each other at the ends of the blades ( 4 ) at virtually the same curvature virtually mathematically tangentially in a plane at right angles to the rotation shaft ( 3 ), as a result of which a more continuous and steady laminar wind flow towards the blades ( 4 ) of the hollow rotor ( 2 ) can be achieved.
  • the curvature of the vanes ( 5 ) in the horizontal plane is defined by a part of a virtually logarithmic spiral. This shape significantly reduces the risk of, for example, turbulences occurring or of the laminarity of the wind being disturbed, as a result of which the efficiency of the wind turbine can be increased further.
  • the wind turbine ( 1 ) preferably also comprises means for converting the rotating movement of the rotor ( 2 ) into electrical energy, such as for example an alternator.
  • An alternator or alternating current generator
  • An alternator is a machine in which mechanical energy, entering via a rotating shaft, in this case the rotor ( 2 ) of the wind turbine ( 1 ), is converted into electrical energy (alternating current). This conversion is based on the fact that when an electrical conductor moves through a magnetic field, electrical voltages are generated in said conductor and current starts to flow if the circuit is closed.
  • an alternator contains the following two parts: the stator, the stationary part, and the rotor, the rotating part.
  • the magnetic field may be generated by one or more permanent magnets.
  • the stator contains one or more coils in which the desired sinusoidal alternating current voltage is generated by rotating the rotor.
  • an axial flux alternator This is a type of alternator in which the magnets are fitted on discs and the flux between the magnets runs parallel to the rotation shaft of the wind turbine ( 1 ) and this type of alternator is ideal for generating electricity, even when the speed of rotation of the rotor ( 2 ) is low.
  • the wind turbine ( 1 ) may also be driven by wind which is, for example, supplied by a compressed air hose ( 7 ) to the rotor ( 2 ), as is shown in FIG. 4 .
  • the compressed air which is supplied to the rotor ( 2 ) via the compressed air hose ( 7 ) is intended to contribute to reaching a critical rotary velocity, above which the efficiency of the wind turbine ( 1 ) increases significantly.
  • the compressed air may, for example, also be replaced by pressurized water or steam or still other fluids.
  • Another possibility in this context is, for example, to drive the wind turbine ( 1 ) using the air displacement of a condenser ( 8 ) of an air-conditioning system which may be situated on a roof, as is illustrated in FIG. 5 .
  • the air displacement which is caused by a condenser ( 8 ) of an air-conditioning system may be caught by the vanes ( 5 ) which are arranged around the rotor ( 2 ) and which thus drive the rotor ( 2 ). Therefore, due to the wind turbine according to the invention, the air flow of the condenser ( 8 ) can be converted into clean energy.
  • Yet another possibility involves the use of the air displacement caused by a ventilation system by fitting the wind turbine ( 1 ) above the ventilation duct and to guide the air displacement towards the rotor ( 2 ) of the wind turbine ( 1 ).
